I thought the boss fight in Halo 2 was a load of rubbish. I've had harder fights battling newbies online.

Snake vs Liquid was a poor beat-em-up thing. Man to go from Rex to that was a let down.

gurral War, that guy in the end suit in the end, he was hard to beat, he keep thowing bombs at me. That sure took a lot of money that one day.

Humanoid gannon in ocarina of time (reflecting those energy bombs was kickass).. and it disgusts me that games still havent learned how to do good real time combat from this game. (but anyway lol)
